I think I know the answers to these but I'm asking to just confirm I'm right.
All questions are about how these things affect the ball's behavior.
1. PAP to Pin distance, determines what?
2. Pin above or Pin below the fingers drillings, determines what?
3. The angular relationship between a line drawn thru the PAP & Pin versus a line thru the Pin & CG or MB, determines what?
4. Does the Pin length affect how a ball performs or is the different lengths only intended to aid whatever drilling you're looking to put in the ball?
